Wisdom Tooth Extraction

Wisdom teeth can be very tricky things. Sometimes they behave themselves and grow straight and don't give any problems, however a lot of the time they tend grow sideways into other teeth and become impacted. In these cases the wisdom tooth will need to be extracted. As with all extractions the dentist will need to take an x-ray to check underneath the tooth and make sure there are no abnormalities such a curved roots, abscesses etc. In the case of wisdom teeth the dentist will most likely need to take a OPG Jaw scan, which is a special machine that takes an x-ray of the whole jaw and enables the dentist to see the problem tooth easier. When the dentist has collected the information from his x-ray, he then decides if it is a straight forward extraction or if it is a more complicated one, such as a surgical extraction which is determined by the severity of abnormalities mentioned above.

Wisdom teeth can cause all kinds of problems. So just what is their function, why do they cause such trouble and what issues surround their removal? Here are some frequently asked questions.

Why do we call them "wisdom teeth"?

Wisdom teeth usually start erupting at around 17-25 years old, which led them to be name by 1848 because we're a little older and wiser than we were in our formative years.

Why do we even have wisdom teeth?

Some believe that Wisdom teeth are a remnant from our primitive ancestors who needed those four extra molars to help chew their hunter-gatherer diet of sinewy, raw meat and tree bark and so forth. The advent of cooking and meal preparation created cuisine that was softer and easier to chew, thus eliminating the need for the additional molars.
